Hi All,
I managed to get the new EMI2 head node up and running last week after
fixing my minor screw up with the permissions. However, the performance
is *terrible* compared to the previous Glite install. I had thought it
was to do with running it on a VM, but I reinstalled on a baremetal
machine today (actually better spec than the original one) and I see the
same problem. Basically, it starts OK, then it begins to take ages to
take the SRM request and offload it to the pool node. A simple lcg-cr
for example would take ~5s previously but on the new one can take up to
20s! This goes on a few a few hours and then services (dpm, srmv2.2,
dpns) start randomly falling over and won't stay up for any great length
of time.
I'm guessing there is some tuning I should have done but I haven't found
anything to tell me what :( Has anyone seen this before??
Thanks!
Mark
